CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a National Phase Application of International Application No. PCT/CN2015/095114, filed on Nov. 20, 2015, which claims priority to and benefit of Chinese Patent Application No. 201410836009.6, filed on Dec. 27, 2014, and entitled “Communications Method and Apparatus”, each of which is herein incorporated by reference in its entirety.

TECHNICAL FIELD

Embodiments of this application generally relate to the field of communications technologies, and in particular, to communications methods and user equipment.

BACKGROUND

Due to the limited power, a large number of sensor devices and wearable devices tend to use a low power consumption network technology in wireless connection, such as Zigbee and Bluetooth Low Energy (BLE). This type of network usually supports a variable connection interval so that the most appropriate transmission frequency is used according to particular data transmission demands, thus reducing energy consumption.

Taking a BLE as an example, after a data connection is established, a device can set or change at least one connection parameter. Specifically, the BLE provides two connection parameters. One is a connection interval, that is a data sending interval between a master device and a slave device, and the value range of the interval is from 7.5 ms to 4.0 s. The other is a slave device delay that is the number of connection intervals the slave device is allowed to delay monitoring. In this way, the slave device can skip several connection intervals before executing one monitoring, which further reduces energy consumption thereof.

In some application scenarios, a user needs to quickly access and check data. For example, a user wearing a smart wristband wants to check physical feature data on a mobile phone that is connected to the smart wristband. At this moment, the connection parameters need to be adjusted to accelerate the speed of data acquisition. However, the data transmission interval between devices is usually relatively big. Although the user can set a smaller connection interval, the setting instruction needs to wait for the next transmission opportunity to be sent to a peer device. In other words, a relatively long time still needs to be taken before completing adjustment of the connection parameters, and further to communicate with the peer.

DETAILED DESCRIPTION

Implementation manners of this application are described in the following in more detail with reference to the accompanying drawings and the embodiments. The following embodiments are used to describe this application, but not to limit the scope of this application.

FIG. 1 is a schematic flowchart of Embodiment 1 of a communications method that is provided by this application. As shown in FIG. 1, this embodiment comprises:

110. A user equipment obtains at least one signal value that is generated based on contact between the user equipment and a human body, and the human body is also in contact with another user equipment.

In this embodiment, each of the user equipment and the another user equipment can be any device that can interact with a user, comprising but not limited to: a handheld device, a wearable device, etc., wherein the handheld device comprises but is not limited to: a mobile phone, a pad (PAD), etc.; and the wearable device comprises but is not limited to: a smart wristband, a smart ring, etc.

In this embodiment, the equipment type of the another user equipment and that of the user equipment can be the same or can be different. For example, the user equipment is a mobile phone, and the another user equipment is another mobile phone or a pad; and the user equipment is a mobile phone, and the another user equipment is a smart wristband.

In this embodiment, the user equipment can be in contact with any part of the human body. For example, when the user equipment is a mobile phone, the user equipment is optionally in contact with a finger, a palm, or other part of the human body; and when the user equipment is a smart wristband, the user equipment is optionally in contact with a finger, a palm, a wrist, or other part of the human body.

In this embodiment, the another user equipment can be in contact with any part of the human body. For example, when the another user equipment is a mobile phone, the another user equipment is optionally in contact with a finger, a palm, or other part of the human body; and when the another user equipment is a smart wristband, the another user equipment is optionally in contact with a finger, a palm, a wrist, or other part of the human body.

In this embodiment, the at least one signal value may be one signal value or multiple signal values.

In this embodiment, the at least one signal value can be generated at the beginning when the user equipment contacts with the human body, or be generated at the time when the another user equipment contacts with the human body during the process that the user equipment is being in contact with the human body.

120. Determine at least one transmission parameter at least according to the at least one signal value and a preset transmission parameter rule.

In this embodiment, at least one transmission parameter can be one transmission parameter or multiple transmission parameters.

In this embodiment, the at least one transmission parameter comprises but is not limited to at least one of the following: a transmission channel, a transmission delay, and a codeword,

wherein the transmission channel refers to a data signal transmission channel in which wireless signals act as transmission medium. For example, for a frequency hopping communication, a hopping sequence number (HSN) can be used to identify the transmission channel,

wherein for a sender of information, the transmission delay is used to determine beginning time of sending the information, and for a receiver of the information, the transmission delay is used to determine beginning time of receiving the information,

wherein the codeword is also known as a code pattern; for the sender of the information, the codeword is used to encode the information to be sent, and for the receiver of the information, the codeword is used to decode the information received.

In this embodiment, the transmission parameter rule comprises: a corresponding relationship of at least one signal value and at least one transmission parameter, and/or a corresponding relationship of at least one signal value range and at least one transmission parameter.

In the scenario that the transmission parameter rule comprises the corresponding relationship of at least one signal value range and at least one transmission parameter, error of the at least one transmission parameter that is caused by measurement error of the at least one signal value can be reduced to a certain degree.

130. Communicate with the another user equipment at least according to the at least one transmission parameter.

In this embodiment, since the user equipment and the another user equipment are both in contact with the human body, during the process that the user equipment performs step 110 to step 120, the another user equipment can also obtain at least one corresponding signal value, and determine at least one transmission parameter that is the same as that determined by the user equipment, based on the same transmission parameter rule, so that the user equipment and the another user equipment can communicate with each other based on at least one same transmission parameter.

In this embodiment, the communications contents of the user equipment and the another user equipment can be of multiple types, such as an instruction, sensor data, and a connection parameter that needs to be set.

In this embodiment: obtaining, by a user equipment, at least one signal value that is generated based on contact between the user equipment and a human body, wherein the human body is also in contact with another user equipment; determining at least one transmission parameter at least according to the at least one signal value and a preset transmission parameter rule; communicating with the another user equipment at least according to the at least one transmission parameter, a communications solution between devices is provided. And determining at least one transmission parameter for communication between devices through an out-band method can achieve quick and convenient communication.

The methods of this embodiment will now be further described by way of the following optional implementation manners.

In this embodiment, the at least one signal value can have multiple implementation manners.

In an optional implementation manner, the at least one signal value is a static electricity variation of the user equipment.

Specifically, the static electricity variation is an electrostatic charge variation.

Specifically, the static electricity variation is an increment of the static electricity or a decrement of the static electricity.

In a possible scenario, the user equipment contacts with the human body first, and collects the electrostatic charges of the human body to make the amount of the electrostatic charges of the human body 0 or close to 0. Then during the process that the user equipment is being in contact with the human body, the another user equipment contacts with the human body. At this moment, electrostatic charges of the another user equipment are transferred to the human body, and the electrostatic charges that are transferred to the human body are also collected by the user equipment. Therefore, the static electricity variation of the user equipment is equal to or is almost equal to the static electricity variation of the another user equipment, and the static electricity variation of the user equipment and the static electricity variation of the another user equipment are the same in terms of amount, but differ in the direction of variation, that is, the increment of the static electricity of the user equipment is equal to or is substantially equal to the decrement of the static electricity of the another user equipment.

In another possible scenario, the another user equipment contacts with the human body first, and collects the electrostatic charges of the human body to make the amount of the electrostatic charges of the human body 0 or close to 0. Then during the process that the another user equipment is being in contact with the human body, the user equipment contacts with the human body. At this moment, electrostatic charges of the user equipment are transferred to the human body, and the electrostatic charges that are transferred to the human body are also collected by the another user equipment. Therefore, the static electricity variation of the user equipment is equal to or is almost equal to the static electricity variation of the another user equipment, and the static electricity variation of the user equipment and the static electricity variation of the another user equipment differ merely in the direction of variation, that is, the decrement of the static electricity of the user equipment is equal to or is substantially equal to the increment of the static electricity of the another user equipment.

In this implementation manner, the transmission parameter rule comprises: a corresponding relationship of a static electricity variation and at least one transmission parameter, and/or a corresponding relationship of a static electricity variation range and at least one transmission parameter.

For example, under the transmission parameter rule, a static electricity variation 50 mC is corresponding to a transmission delay of 5 ms, and a static electricity variation 100 mC is corresponding to a transmission delay of 10 ms. For another example, under the transmission parameter rule, a static electricity variation range [50 mC, 60 mC) is corresponding to a transmission delay of 5 ms and a first codeword, and a static electricity variation range [100 mC, 110 mC) is corresponding to a transmission delay of 10 ms and a second codeword.

In another optional implementation manner, the at least one signal value is at least one change frequency of an equivalent capacitance on the user equipment side,

wherein the equivalent capacitance on the user equipment side is the equivalent capacitance that is detected on the user equipment side.

Specifically, since the user equipment and the another user equipment are both in contact with the human body, the equivalent capacitance on the user equipment side is at least affected by the capacitance value of the human body and the capacitance value of the another user equipment.

In the implementation manner, optionally, the another user equipment controls the capacitance value of the another user equipment itself to change at the at least one frequency, wherein the capacitance value of the another user equipment itself refers to a capacitance value of ground capacitance of the another user equipment. Correspondingly, when the user equipment and the another user equipment are both in contact with the human body, the user equipment can detect the change, and obtains the at least one frequency.

In a possible scenario, the user equipment is a smart wristband. When the smart wristband is worn on a wrist of the human body, FIG. 2A is a schematic circuit diagram of an equivalent capacitance when the user equipment is in contact with the human body. As shown in FIG. 2A, Cwd is a capacitance between the wrist and the smart wristband, Cdh is a capacitance between the smart wristband and the human body, Cd is a capacitance of the smart wristband itself, Ch is a capacitance of the human body itself, and Cx is an equivalent capacitance on the user equipment side.

In this scenario, the another user equipment is a mobile phone. When the human body touches the mobile phone with a finger of the hand that wears the smart wristband, FIG. 2B is a schematic circuit diagram of equivalent capacitances when the user equipment and the another user equipment are both in contact with the human body. As shown in FIG. 2B, Cx,wd is the capacitance between the wrist and the smart wristband. Cx,dh is the capacitance between the smart wristband and the human body. Cx,d is the capacitance of the smart wristband itself. Ch is the capacitance of the human body itself. Cy,fd is a capacitance between the finger and the mobile phone. Cy,dh is a capacitance between the mobile phone and the human body. Cy,d is a capacitance of the mobile phone itself, Cx′ is an equivalent capacitance on the user equipment side, and Cy′ is an equivalent capacitance on the another user equipment side. It can be seen from FIG. 2B that when the Cy,d changes at at least one frequency, the Cx′ also changes correspondingly at the at least one frequency. Therefore, the at least one frequency can be detected on the user equipment side.

In the implementation manner, the transmission parameter rule comprises: a corresponding relationship of at least one frequency and at least one transmission parameter, and/or a corresponding relationship of at least one frequency range and at least one transmission parameter.

For example, under the transmission parameter rule, 50 Hz is corresponding to a transmission delay of 5 ms and a first codeword, and 80 Hz is corresponding to a transmission delay of 8 ms and a second codeword. For another example, under the transmission parameter rule, [50 Hz, 60 Hz) is corresponding to a first codeword, and [80 Hz, 90 Hz) is corresponding to a second codeword.

In another optional implementation manner, the at least one signal value is a coupling capacitance value at the location where the user equipment is in contact with the human body.

For example, a finger of the human body is in contact with a capacitive touch screen of the user equipment. The contact of the finger corresponds to a parallel connection of a coupling capacitor in the contact location of the capacitive touch screen to cause a change of current and voltage of a sensor circuit of the capacitive touch screen. Correspondingly, the user equipment can determine the capacitance value of the coupling capacitor based on the change of the current and the voltage of the sensor circuit, that is, the coupling capacitance value.

In this implementation manner, optionally, the determining at least one transmission parameter at least according to the at least one signal value and the preset transmission parameter rule comprises:

determining an induced charge quantity generated from the location where the human body is in contact with the user equipment at least according to the coupling capacitance value and the transmission parameter rule;

determining the at least one transmission parameter at least according to the induced charge quantity.

Specifically, a corresponding relationship of the induced charge quantity and the coupling capacitance value can be obtained through learning in advance. Correspondingly, according to the corresponding relationship and the coupling capacitance value actually obtained in step 110, the induced charge quantity can be determined.

In the implementation manner, the transmission parameter rule comprises: a corresponding relationship of induced charge quantity and at least one transmission parameter, and/or a corresponding relationship of induced charge quantity range and at least one transmission parameter.

For example, an induced charge quantity 50 mC is corresponding to a first transmission channel, and an induced charge quantity 100 mC is corresponding to a second transmission channel. For another example, an induced charge quantity range [50 mC, 100 mC) is corresponding to a first transmission channel, a first codeword and a transmission delay of 5 ms. An induced charge quantity range [100 mC, 50 mC) is corresponding to a second transmission channel, a second codeword and a transmission delay of 10 ms.

In a possible scenario, the another user equipment contacts with the human body first, and collects the electrostatic charges of the human body to make the amount of the electrostatic charges of the human body 0 or close to 0. Then during the process that the another user equipment is being in contact with the human body, the user equipment contacts with the human body. At this moment, induced charges are generated at the location where the human body is in contact with the user equipment. The charge quantity of the induced charges decides the coupling capacitance value at the location where the user equipment is in contact with the human body. At the same time, charges that are generated at the location where the human body is in contact with the user equipment is collected by the another user equipment, the charge quantity of which is equal to that of the induced charges and the polarity of which is opposite to that of the induced charges. Therefore, the induced charge quantity that is determined by the user equipment is equal to or is almost equal to the static electricity variation of the another user equipment. The induced charge quantity that is determined by the user equipment and the static electricity variation of the another user equipment merely differ in the polarity of the charges.

FIG. 3 is a schematic flowchart of Embodiment 2 of a communications method that is provided by this application. As shown in FIG. 3, this embodiment comprises:

310. A user equipment controls a capacitance value of the user equipment to change at at least one frequency.

In this embodiment, the capacitance value of the user equipment itself is a capacitance value of ground capacitance of the user equipment.

In this embodiment, there can be multiple methods through which the user equipment may control the capacitance value change of the user equipment. For example, the user equipment controls the capacitance value change of a changeable capacitor of the user equipment to make the capacitance value of ground capacitance of the user equipment change, wherein the changeable capacitor can be set on a circuit board of the user equipment.

In this embodiment, the at least one frequency may be one frequency or multiple frequencies.

320. Determine at least one transmission parameter at least according to the at least one frequency and a preset transmission parameter rule.

In this embodiment, the at least one transmission parameter may be one transmission parameter or multiple transmission parameters.

In this embodiment, the at least one transmission parameter comprises but is not limited to at least one of the following: a transmission channel, a transmission delay, and a codeword,

wherein the transmission channel refers to a data signal transmission channel in which wireless signals act as transmission medium. For example, for a frequency hopping communication, an HSN can be used to identify the transmission channel,

wherein for a sender of information, the transmission delay is used to determine beginning time of sending the information, and for a receiver of the information, the transmission delay is used to determine beginning time of receiving the information,

wherein the codeword is also known as a code pattern; for the sender of the information, the codeword is used to encode the information to be sent, and for the receiver of the information, the codeword is used to decode the information received.

In this embodiment, the transmission parameter rule comprises: a corresponding relationship of at least one frequency and at least one transmission parameter, and/or a corresponding relationship of at least one frequency range and at least one transmission parameter.

For example, 50 Hz is corresponding to a transmission delay of 5 ms, and 80 Hz is corresponding to a transmission delay of 10 ms. For another example, 50 Hz and 60 Hz are corresponding to a transmission delay of 5 ms, and 70 Hz and 80 Hz are corresponding to a transmission delay of 10 ms. For another example, a frequency range [50 Hz, 60 Hz) is corresponding to a transmission delay of 5 ms and a first codeword, and a frequency range [60 Hz, 70 Hz) is corresponding to a transmission delay of 6 ms and a second codeword.

In this embodiment, the sequence of step 310 and step 320 can be arbitrary. For example, step 310 is performed first then step 320 is performed. Or step 320 is performed first then step 310 is performed. Or step 310 and step 320 are performed simultaneously.

330. Communicate with another user equipment at least according to the at least one transmission parameter, and the user equipment and the another user equipment are both in contact with a human body.

In this embodiment, the another user equipment can be any device that can interact with a user, comprising but not limited to: a handheld device, a wearable device, etc., wherein the handheld device comprises but is not limited to: a mobile phone, a pad (PAD), etc.; and the wearable device comprises but is not limited to: a smart wristband, a smart ring, etc.

In this embodiment, the equipment type of the another user equipment and that of the user equipment can be the same or can be different. For example, the user equipment is a mobile phone, and the another user equipment is another mobile phone or a pad; and the user equipment is a mobile phone, and the another user equipment is a smart wristband.

In this embodiment, the user equipment can be in contact with any part of the human body. For example, when the user equipment is a mobile phone, the user equipment is optionally in contact with a finger, a palm, or other part of the human body; and when the user equipment is a smart wristband, the user equipment is optionally in contact with a finger, a palm, a wrist, or other part of the human body.

In this embodiment, the another user equipment can be in contact with any part of the human body. For example, when the another user equipment is a mobile phone, the another user equipment is optionally in contact with a finger, a palm, or other part of the human body; and when the another user equipment is a smart wristband, the another user equipment is optionally in contact with a finger, a palm, a wrist, or other part of the human body.

In this embodiment, the user equipment and the another user equipment are both in contact with the human body. The equivalent capacitance in the scenario is as shown in FIG. 2B. Therefore, when the user equipment performs step 310, the another user equipment can obtain the at least one frequency, and determine at least one transmission parameter that is the same as that determined by the user equipment based on the same transmission parameter rule, so that the user equipment and the another user equipment can communicate with each other based on the same at least one transmission parameter.

In the scenario that the transmission parameter rule comprises the corresponding relationship of at least one frequency range and at least one transmission parameter, error of the at least one transmission parameter that is caused by measurement error of the at least one frequency of the another user equipment can be reduced to a certain degree.

In this embodiment, the communications contents of the user equipment and the another user equipment can be of multiple types, such as an instruction, sensor data, and a connection parameter that needs to be set.

In this embodiment, a user equipment controls the capacitance value of the user equipment to change at at least one frequency, determines at least one transmission parameter at least according to the at least one frequency and a preset transmission parameter rule, and communicates with another user equipment at least according to the at least one transmission parameter. The user equipment and the another use equipment are both in contact with a human body. A communications solution between devices is provided, and determining at least one transmission parameter for communication between devices through an out-band method can achieve quick and convenient communication. The methods of this embodiment will now be further described by way of the following optional implementation manners.

Correspondingly, in step 310, the user equipment can control the capacitance value of the user equipment to change into C2 when t=1/f1, and controls the capacitance value of the user equipment to change into C1 when t=2/f1. Or in step 310, the user equipment can control the capacitance value of the user equipment to gradually change into C2 from C1 during the time when t=0˜1/f1, and controls the capacitance value of the user equipment to gradually change into C1 from C2 when t=1/f1˜2/f1.
